- Engine Overheating: The engine cooling system has sometimes been problematic. If not addressed, leaks in the radiator, thermostat failures, or malfunctioning water pumps can cause overheating, leading to severe engine damage.
What Can Be Done?
Regular maintenance is essential to avoid or fix these problems. Ensure that the engine is checked regularly for leaks and that oil levels are monitored. If you experience engine knocking, inspect it as soon as possible. In some cases, engine component replacements or adjustments may be necessary to correct these issues.
3.7-litre V6 Engine
A few other concerns may arise for those who chose the smaller 3.7-litre V6 engine.
Common Problems with the 3.7-litre V6 Engine
- Head Gasket Failure: One of the most frequently reported issues with the V6 engine is the failure of the head gasket. Left untreated, this can lead to coolant and oil mixing, causing serious engine damage.
- Stalling or Rough Idling: Some owners have experienced rough idling or stalling, especially during acceleration. Faulty sensors or clogged fuel injectors often cause this.
- Timing Chain Problems: Some Jeep Commander owners have reported issues with the timing chain stretching or failing, which can cause engine misfires or even complete engine failure if not replaced in time.
What Can Be Done?
Regularly replacing spark plugs, air filters, and oil can help avoid some of these issues. If you notice rough idling or stalling, visiting a mechanic to inspect the fuel system and sensors can help identify the problem early.
Transmission Troubles
Transmission Slipping
A common problem with older Jeep Commanders is transmission slipping. This can occur when the transmission unexpectedly changes gears or fails to engage smoothly, causing jerking or hesitation while driving.
Causes of Transmission Slipping
- Low Transmission Fluid: Low or dirty transmission fluid is one of the most common causes of slipping. This fluid helps lubricate the transmission and keep it operating smoothly.
- Worn Clutch Plates or Bands: Over time, the internal components of the transmission, such as clutch plates or bands, can wear out, leading to slipping and shifting issues.
- Faulty Solenoids: The transmission solenoids help control the flow of transmission fluid. If they malfunction, it can result in improper shifting.
What Can Be Done?
If your Commander is experiencing transmission slipping, check the fluid levels and condition. If the fluid is low or dirty, a flush and refill may solve the problem. If the slipping persists, replacing the clutch plates, bands, or solenoids may be necessary.
Transmission Failure
Some Jeep Commander owners have reported complete transmission failure, particularly on the 5.7-litre Hemi models. This problem can be an expensive problem to fix, often requiring a full transmission replacement.
What Can Be Done?
Regular fluid changes and monitoring the transmission’s behaviour can help prevent significant transmission failures. If you notice any unusual shifting patterns or hear strange noises, a professional must check the transmission before a failure occurs.
Suspension and Steering Issues
Suspension System Problems
The Jeep Commander’s suspension system, particularly the front suspension, has been known to wear out prematurely. This can lead to excessive noise, a rough ride, and difficulty handling.
Common Problems with Suspension
- Worn-out Ball Joints: The ball joints in the suspension system can wear out, causing a clunking sound when turning the steering wheel or driving over bumps.
- Broken or Weak Springs: Over time, the suspension springs may lose their ability to support the vehicle properly, leading to a sagging stance and reduced ride quality.
- Shocks and Struts Failure: The shocks and struts absorb the impact of bumps and rough terrain. If these components fail, the ride will become bouncy and uncomfortable.
What Can Be Done?
Regularly inspect the ball joints, springs, and shocks to maintain the suspension system. Replacing worn-out components will restore the ride’s smoothness and stability.
Power Steering Failures
Another frequent issue reported by Jeep Commander owners is power steering failure. This typically manifests as difficulty steering, particularly at low speeds.
Causes of Power Steering Problems
- Leaking Power Steering Fluid: Leaks in the power steering system can cause fluid levels to drop, resulting in heavy, unresponsive steering.
- Faulty Power Steering Pump: A failing power steering pump can cause inconsistent or no power assist when steering.
What Can Be Done?
If your Jeep Commander is experiencing power steering issues, check the fluid levels and inspect the steering pump for leaks. Replace the pump or steering rack to restore proper steering functionality.
Electrical and Interior Problems
Electrical System Failures
The electrical system in the Jeep Commander can be a source of frustration, particularly with the various sensors, control modules, and wiring that control everything from the engine to the airbags.
Common Electrical Problems
- Faulty Alternator: Some owners have reported issues with the alternator failing prematurely. This can lead to a dead battery, leaving you stranded.
- Sensor Failures: The Jeep Commander has numerous sensors that monitor engine performance, emissions, and safety systems. If these sensors fail, it can trigger the check engine light or cause the vehicle to operate poorly.
- Flickering or Dead Dashboard Lights: Another common electrical issue involves dashboard lights flickering or completely dying, which could indicate problems with the wiring or the dashboard module.
What Can Be Done?
Regularly inspect the battery and alternator to ensure proper charging. If any electrical components fail, replacing them promptly can prevent more serious issues from developing.
Interior Problems
While the Jeep Commander offers a spacious and comfortable interior, it has flaws.
Common Interior Problems
- Seat Stuck in Position: Some owners have complained about the seats, particularly the power-adjustable ones, getting stuck in a particular position or failing to move.
- Faulty Air Conditioning: The Commander’s air conditioning system has been known to malfunction, especially in older models. This can lead to poor cooling performance or complete failure.
